I'm not sure what kind of answers you are expecting, and am especially curious why you are posting new questions when 4 days ago you were requesting your forum account deleted - so I guess you could say that I sense troll-like activities.

The technical differences between the two are to the best of my knowledge untold so far - mostly conceptual/behavioural differences separate them at this time. The people behind "siduction" have a strong difference of opinion about the way the people behind "aptosid" conduct themselves in developing and supporting a FOSS distribution, so they decided to copy everything to somewhere else and started moving on with whatever it is that they want to change.

I am not aware of all differences which caused the "siduction" people grief, but transparency of development seemed to pop up every now and then, a willingness for aptosid people to ignore the perceived user-pain caused by breakage of non-free software was another.
